WELCOME TO ACADIA NATIONAL PARK
Letter from the Superintendent
Dear Guide User,
You are an important partner of the National Park Service. The 2012 Guide’s Guide helps meet
the standards set forth in the Commercial Services Plan by providing you with a better
understanding of Acadia’s resources, significance, and need for low impact visits. Some visitors
discover Acadia on their own, while others do so with an organized group—either private or
commercial. Because of the large number of commercial users in and around Acadia, park
managers request that commercial activities contribute to the sustainability of park resources,
enhance educational opportunities, and offer quality interpretation.
Whether you are a bus tour guide searching for more specific information, a supervisor training
staff to work with visitors, or a business owner needing park information to answer customer
questions, the Guide’s Guide will provide you with the tools to:
• Impart to visitors the primary purpose of Acadia National Park.
• Understand some of the unique natural and historical aspects of Acadia.
• Deliver accurate information to improve interpretation to visitors using commercial
services.
• Magnify the impact of park conservation messages.
• Apply Leave No Trace principles in each park area.
Please familiarize yourself with this section before beginning the rest of the Guide’s Guide. We
hope this material will be part of an effective trip to Acadia National Park. Whatever your
intent—exploring habitats of ecological importance, reflecting on historical events of both local
and national value, or simply enjoying the exceptional opportunities for inspiration and
recreation—your efforts to further the park’s mission with your group assure the continued
protection of Acadia as a national treasure.
Thank you for your cooperation. Enjoy the park!
Sincerely,
Sheridan Steele
Park Superintendent

Acadia National Park – A Place Like No Other
“It is a true park area in the highest sense, totally different from any other that we have.”
“It is rich in historic association, in scientific interest, and in landscape beauty.”
“There is no other place along the Atlantic coast where so wide a range of geologic facts are
shown or where such valuable material is offered for research.”
“It will give a healthy playground to multitudes of hard-working men and women.”
“With its adjacent inlets and headlands, it stands out as offering the greatest natural diversity.”
—excerpts from letters to President Woodrow Wilson in support of the park’s creation
The above lines, written in the early 1900s in support of the creation of a national park on
Mount Desert Island along the coast of Maine, are as applicable today as when they were first
penned. The foresight of stewardship-minded individuals at the turn of the 19th century created
this first national park east of the Mississippi in 1916. Private citizens, through their generous
donations of land, gave this gift to the American people. Granite mountain tops, sparkling
lakes, forested valleys, meadows, marshes, and rocky coastline weave together to create a
national park like no other. Acadia’s landscape holds human history as well, from American
Indians and European explorers to a seafaring population and conservationists. Acadia’s
resources are not found in oil or lumber, but in undisturbed natural systems for study,
exceptional scenery for individual inspiration, protected habitat for plants and animals, and
defining stories of people and the land. The National Park Service at Acadia is charged by
federal law to protect and conserve Acadia’s outstanding scenic and natural resources and
cultural identity for present and future generations. Through this mission, preservation,
education, scientific research, and recreation opportunities abound.
Acadia, like other national parks, offers opportunities to fulfill emotional and spiritual
needs for renewal and to invoke attitudes of reverence and stewardship. Because of the
deep affection held for Acadia, private citizens of both a century ago and today took the actions
necessary to preserve these beautiful landscapes. As a national park, Acadia has continued the
tradition of providing spiritual respite and encouraging responsible stewardship. Acadia’s easy
accessibility for all ages and all levels of ability make it possible for everyone to observe and be
renewed by nature.
The flora and fauna of Acadia National Park and surrounding waters comprise a rich mix
of species significant in their biodiversity. Botanically, Acadia lies in a transition zone
between the northern coniferous forests and the temperate deciduous woods. The co-mingling
of species from two distinct regions creates unusual plant associations. Rare and endangered
plant species find refuge here. The variety of vegetation supports a diversity of wildlife as well.
Critical habitat is provided for all animals, especially for protected species and nesting seabirds
on outlying islands.

9. 8
The cultural resources of Acadia National Park document human activities that span
5,000 years. Acadia’s human history begins with centuries of use by native people, who
became known as the Wabanaki. Only five centuries ago, Europeans began making contact
with these people, as they too explored and settled here. Decades of commercial use by
lumbermen, shipbuilders, and fishermen overlapped and even fostered increased pressure for
conservation and the evolution of tourism. Today, over two million visitors each year seek
Acadia’s gifts, either by trail, boat, bicycle, vehicle, or through quiet contemplation.
Acadia National Park provides many opportunities to increase our understanding of
natural systems and human impact on them. Considered a living laboratory since the 19th
century, Acadia offers significant possibilities for education, continued ecosystem monitoring,
and research that generates valuable data. Research conducted by park staff, visiting
researchers, and citizen scientists continue to add to Acadia’s foundation of historic scientific
reports. While a variety of science occurs throughout the park, the Schoodic Education and
Research Center has turned a formal navy base into a focal point for science and education.
The natural landforms of Acadia National Park illustrate the dynamics of many geologic
processes. Exploring Acadia is like walking through a geology textbook with chapters that
include all three rock types, plate tectonics, volcanism, glaciations, and shoreline erosion. The
park’s granite mountains are surrounded by sedimentary and metamorphic rocks, covering a
time span of half a billion years. The awesome power of glaciers is evident in the valleys and
cliff sides, while the on-going assault by the sea reworks the island’s edge even today.
Significant geologic resources include Somes Sound, a glacially sculpted fjord (or fjard); Sand
Beach, a natural pocket beach composed primarily of shell fragments; and a collection of
former sea-level features such as cobble beaches, cliffs, and caves that are now exposed
approximately 240 feet above current sea level.

10. 9
Acadia as Part of the National Park System
The National Park Service preserves some of the most cherished natural and cultural areas of
our nation. Three hundred and ninety-five sites cover more than 84 million acres, encompassing
every state except Delaware. Sites are also found in the District of Columbia, American Samoa,
Guam, Puerto Rico, and the Virgin Islands.
The National Park System includes beautiful and significant natural areas such as seashores,
lakeshores, mountains, canyons, caves, deserts, coral reefs, and geologic wonders. Also
preserved are important pieces of our nation’s history such as battlefields, war sites, American
Indian sites, and the homes of presidents, inventors, civil rights leaders, authors, and others of
national prominence. A site can be called a national park, historic site, historical park,
monument, parkway, lakeshore, seashore or any of 11 other titles. Acadia is one of 58 sites with
national park designation.
In 1872, Yellowstone was the first national park created for a “public park or pleasuring-ground
for the benefit and enjoyment of the people.” Other parks such as Sequoia, Mount Rainier,
Crater Lake, and Glacier were created between the 1890s and early 1900s. Acadia was first
established as Sieur de Monts National Monument by the signature of President Woodrow
Wilson on July 8, 1916, just one month before he signed the act to create the National Park
Service itself on August 25, 1916. The directive given the service was to “…conserve the
scenery and the natural and historic objects and the wild life therein and to provide for the
enjoyment of the same in such manner and by such means as will leave them unimpaired for the
enjoyment of future generations.”
This mission continues into the 21st century. The dual directive to preserve the land, history,
and wildlife while making them available for public enjoyment is challenging. Acadia’s park
policies are derived from this act. Acadia’s specific purpose reads:
1. To protect and conserve the land and water resources, the scenery, the natural and
historic objects, and the biota within the park boundary.
2. To promote and regulate the use of the park for the benefit and enjoyment of the people
in such manner and by such means as will leave the park resources unimpaired for the
enjoyment of future generations.
3. To protect and preserve the scenic, ecological, historic, archeological, and cultural
resources of the Acadian archipelago and to limit development of the islands to preserve
their natural qualities and traditional resource-based land uses.
This is a big job! Merely setting property aside does not guarantee that it is protected. Outside
influences from water pollution, air pollution, and loss of surrounding habitat degrade the
“protected” area inside the park boundary. Park employees are dedicated to protecting the park
and promoting appreciation and stewardship values in park visitors. But we can’t do it alone.
We hope you will share in these efforts and be a partner for protection. After all, Acadia
National Park belongs to all of us, and to our future.
*Letter excerpts from statements by Secretary of the Interior Franklin K. Lane; former President Theodore Roosevelt; Acadia founder George
B. Dorr; David White of the U.S. Geological Survey; and M.L. Fernald of Harvard University.

Weather
Acadia National Park’s weather is largely a product of latitude and marine influences.
Precipitation occurs in every form. Rain falls in every month with an annual average of 48".
The park also has a respectable annual average of 61" of snow. The tempering maritime
conditions, however, with frequent freezing and thawing, prevent large, long-term
accumulations. On a daily and annual basis, Maine temperatures are more severe inland than
they are on Mount Desert Island and on the coast in general.

13. 12
Spring
Spring can be foggy with temperatures ranging between 30 and 70 degrees. Black flies are
common in late May and June. Mosquitoes can also be bothersome. Wear light-colored
clothing, long sleeve shirts and long pants for protection.
Summer
Summer daytime temperatures range from 60 to 85 degrees. Evenings are cooler. Dressing in
layers is advisable for any boating or hiking activities. Ocean water temperatures range from 50
to 60 degrees. Lake water temperatures range from 55 to 72 degrees.
Autumn
Autumn temperatures can range from the low 70s during the day to freezing during the night.
Come prepared for all types of weather, from sun to fog, from downpours to flurries. Fall
foliage often peaks during the first couple of weeks in October.
Winter
Due to Acadia’s coastal location, snow and winter weather conditions change rapidly.
Temperatures vary from mid-30s to below zero. The park averages 61" of snow annually.
For the latest in weather information, call the local weather phone line at (207)667-8910, check
the current weather conditions on the internet, or call the park at (207)288-3338.
Weather Trivia
The Maine coastal climate has been ranked second only to the Pacific Northwest in annual
precipitation. Three localized weather systems dominate Acadia:
• “Smokey sou’wester” In the summer, the typical weather system is a warm flow of air
over the cool Gulf of Maine that produces the heaviest fogs of the year. These
southwesterly patterns are associated with low pressure systems and may last for several
days.
• Bermuda High is the opposite of the southwester. It is a stationary high pressure
system that sits over the Atlantic to the southwest and dominates New England weather
for days. This system repels intruding fronts and weather often becomes hot and humid.
• “Nor’easters” In the winter, these are associated with strong northeast winds that bring
lots of snow and rain to coastal New England.
Frequently Asked Questions
How many days should I spend in Acadia? An average stay here is 3-4 days.
Is there any lodging in the park? Acadia only has two campgrounds, but there are many other
types of accommodations in nearby towns.
What is there for children to do in Acadia? There are many miles of shoreline to explore,
hiking trails to climb, and carriage roads on which to bicycle. Two beaches offer salt water or
fresh water in which to swim. Children of all ages may also participate in the Acadia Junior
Ranger Program. Some of the ranger-led programs are specifically designed for children.

14. 13
Where are pets allowed in the park? Pets are allowed on most hiking trails and carriage
roads, as long as they are on a leash no longer than 6 feet. They are allowed at the campgrounds
as long as they are not left unattended.
Can I leave my pet in the car while I hike? It is not recommended that pets be left in cars,
especially during the summer months.
Where can I see puffins? There are three nesting islands off the coast of Maine. In order to
see puffins, you must take a boat to one of these islands, one of which leaves from Mount
Desert Island. Puffins aren’t seen on or from Mount Desert Island.
What is the origin of “Acadia?” Acadia probably stems from a name given to the area by the
explorer, Giovanni Verrazano, when he sailed by in 1524.The shoreline reminded him of a part
of Greece named Arcadia.
Where does the term Down East come from? During the 18th and 19th centuries, Maine
was a shipping capital. When schooners sailed from Boston to ports in Maine, they traveled to
the east. They also sailed downwind (with the wind at their backs).This led to the expression
“Down East.”
Is it Mount Desert Island or Mount Dessert Island? Samuel Champlain, a French navigator
and cartographer, sailed by Mount Desert Island in 1604. He named it “Isles des Monts Desert,”
with the accent on the last syllable, as it would be in the French language. He wasn’t implying
that it was a desert. The phrase means “island of barren mountains.” That’s why it’s
pronounced both as it is spelled and as the French phrase would be pronounced (dessert).
How far are you from Boston? 264 miles
How long is the loop road and how long will it take to drive it? 27 miles, 3-4 hours
including some stops
What Ranger-led activities are available? Between mid-May and mid-October you may
accompany a ranger on a hike, a shoreline walk, or a boat cruise. Rangers also offer talks on
various subjects, evening amphitheater programs at the campgrounds, children’s programs, and
provide opportunities to view peregrine falcons and raptors.
When does the Island Explorer Shuttle Bus run and where does it go? The Island
Explorer runs between late June and mid-October. It travels between Bar Harbor, Northeast
Harbor, Southwest Harbor and various locations in the park.
How cold is the water at Sand Beach? Between 55-60 degrees F
When can I make reservations for Blackwoods and Seawall? Reservations can be made six
months in advance by calling 877-444-6777, or online at www.recreation.gov.

15. 14
I have never been to Acadia. Should I camp at Blackwoods or Seawall? Some people
prefer to be closer to the main part of the park, the carriage roads, and Bar Harbor, so choose
Blackwoods. Others prefer to be in a more remote area of the island, so choose Seawall. As far
as facilities are concerned, they are the same, and both have wooded sites with no sites directly
on the ocean.
Can I winter camp in Acadia? Yes. You may winter camp at Blackwoods Campground.
Is there backcountry camping in Acadia? No. Backcountry camping is prohibited because
the island is too small and the environment too fragile.
How do I make a group camping reservation? Call or go to our website to download the
form to be mailed or faxed to us. See the Park Activities In-Depth/Camping section for more
information.
When and how can I make reservations to camp at Isle au Haut? Call (207)288-3338 for a
reservation form, or go to our website to download the form. You may then send it to the park
no earlier than April 1 with a $25 special use permit fee.
Does my camping fee cover the entrance fee into the park? No. The two fees are separate.
Are there water and electric hookups in the park campgrounds? No, but there is a dump
station.
Are there any campsites on the ocean in Blackwoods or Seawall campgrounds? No.
They are both a short walk (5-10 minutes) to the ocean.
Are there private campgrounds on the island? Yes, there are about 12 private campgrounds
scattered around the island. We will be glad to send you a list.
When are black flies at Acadia? Usually they are most numerous between mid-May and
mid-June, but that could vary from spring to spring. They breed in running water, so they will
be more prevalent if it is a rainy spring.
How much snow does Acadia receive? Average snowfall in Acadia is about 61".
Can I rent skis nearby? Skis, snowshoes, and skates can be rented in Bar Harbor.
Is the road to Cadillac Mountain open to vehicles in the winter? No. Access is by
snowmobile, skis, or on foot. It is a minimum walk of nine miles round trip. Temperatures on
Cadillac can be well below zero, with extremely high winds and drifting snow.
Can I hike any of the mountain trails in the winter? Hiking mountain trails in the winter is
not recommended. Trail markers and icy patches are obscured by drifting snow creating very
dangerous conditions for hikers.

16. 15
When does the Park Loop Road open and close each year? Each year the Park Loop Road
closes on December 1 and reopens on April 15. The Ocean Drive section remains open all year.
What is the best time to see fall foliage? The leaves start turning their fall colors in
September, but the peak time is usually mid-October.

trip that meets the needs of the participants and protects Acadia. Please familiarize yourself
with the Acadia National Park – A Place Like No Other section and important park
information. Contact park headquarters at (207)288-3338 to check on any current closures or
new policies.
The Commercial Use Authorizations which are available on our website (www.nps.gov/acad,
under park management/Doing business with the park), outlines many other objectives and
requirements for commercial users.
Accessibility Checklist
If needed, arrangements can be made to provide a sign language interpreter on park programs.
Reservations for an interpreter must be made well in advance for scheduling purposes. Call
(207 288-3338, voice; or (207)288-8800, TTY for more information.
• Familiarize yourself with the Welcome to Acadia section and appropriate sections of the
guide.
• Check the park website for further information
• After reading this guide and checking the park website, www.nps.gov/acad, contact the
park via email at or (207)288-3338 if you have further questions.
• More detailed hiking maps, guides, and other books are available through mail-order at
Eastern National or purchase at park visitor centers. See the Eastern National book list
on our website for further information.
• Take time to thoroughly plan your visit, taking into consideration the group’s interests,
abilities and time constraints.
• Consider your group size. Larger groups should go to areas that can handle them rather
than areas that can only handle smaller groups. Consider dividing your group if it is
large.
• Make arrangements at specific locations for your group, i.e. Jordan Pond House,
Wildwood Stables, and the Abbe Museum.
• Know where the restrooms are.
• Be prepared for the weather.
• Good appropriate shoes are especially important. Sneakers are adequate for most easy
trails. Hiking boots are recommended for moderate and strenuous hikes. Shoes with
non-slippery soles are a must for shoreline exploration.
Basic Information to Share and Remember Throughout the
Trip
• Remain on paved walkways and established hiking trails.
• Refrain from stepping on soil and fragile plants.
• Take your trash with you or properly dispose of it in a trash receptacle. Even if it is
biodegradable, peanut shells, orange peels, egg shells, etc. are unsightly and not good
for wildlife.

24. 23
• Avoid disturbing wildlife by refraining from chasing, stalking, and especially feeding
animals.
• Take only pictures. Do not remove rocks, inhabited shells, plants, flowers, cultural
artifacts, etc. from the park. Those who choose to do so affect the landscape of the park.
For the enjoyment of all, please leave things where you find them.
• Keep it quiet. Please limit the use of modern conveniences. If using cell phones or GPS
devices use them discreetly.

Providing an Introduction to Acadia for Your Group
Acadia’s rounded-granite mountains, forested valleys, large lakes, small ponds, marshes, rocky
headlands, and quiet coves await discovery in this small national park. These environments are
home to over 1,100 plant species, 40 mammal species, over 300 birds and a multitude of
smaller creatures.
Recreational opportunities abound within this inspirational setting. Strenuous mountain climbs
and leisurely walks await those who venture from their vehicle. Carriage roads for use by
walkers, bikers, or horses make Acadia accessible for all. Many lakes and ponds are popular for
canoeing, kayaking, and fishing. Boat cruises take advantage of the ocean environment.
Visitors today are a current page in the history of this land. Pre-historic people and the historic
Wabanaki Indians inhabited this land long before Samuel Champlain named it the “Isles des
Monts Deserts.” After 150 years of quarreling between the French and English for claim of
North America, European settlers came in earnest, joining the Wabanaki in taking advantage of
the ocean’s proximity and the island’s generous resources. The mid-1800s brought visitors who
saw those same resources as a spring of inspiration and respite. Some worked to create a
sanctuary that became Acadia National Park.
More than two million people visit Acadia each year. Like those who came before us, we will
leave with our own unforgettable impression of Acadia National Park.
After giving this park introduction, review your itinerary with your group. Explain time
expectations, safety concerns, and any other information you feel is necessary for them to know.

26. 25
SCHOOL GROUPS – EDUCATIONAL ACTIVITIES
“I hear and I forget. I see and I remember. I do and I understand.”
This is the essence of a visit to Acadia National Park where education is active, experiential,
and fun. Acadia helps textbooks and lesson plans come to life through a multitude of
experiences, whether discovering a frog at the edge of a pond, exploring the past at the Islesford
Historical Museum, or observing the diversity of life in a tidepool.
Please remember to always follow good stewardship practices during your visit to Acadia
National Park. Bring only memories (and students!) home with you. We hope you and your
students find Acadia a perfect extended classroom!
Programs for Educational Groups
The park offers ranger-led programs in natural and cultural history topics for third through
eighth grade classes, primarily in the local school districts. School groups beyond the local area
may request a special program by contacting Acadia’s education coordinator at (207)288-8812.
Creating Your Own Program
Teacher guides to each of Acadia’s curriculum-based programs are available free on the park
web site to all teachers or other group leaders interested in planning their own educational trip
to the park. Titles include: Junior Rangers, Animals of Acadia, Carroll Homestead, Shoreline
Discovery, Island Life, Where in the World is Tuzigoot?, and Fire and Ice (geology). The
background information and pre and post activities in the teacher guides can help to design your
own program.
Also available for sale is The Activity Guide to Acadia National Park, which covers animals,
shoreline, and geology in a more detailed format than the free teacher guides. The Teacher
Resource Library at the park’s education office offers over 500 book titles as well as videos for
loan. Two traveling trunks with tactile components and designed for 5th- 8th grades can be
borrowed for up to a month. Both kits have a social studies focus: “Passamaquoddy History and
Culture” and “St. Croix 1604.” Contact the education office to reserve these interactive
resources.
The ranger-led programs during the summer can serve as excellent resources for teachers who
are interested in learning more about the nature and history of this area to enrich their lessons.
The activity schedules can be found at any ranger contact station in the park and also on the
park web site. Acadia’s interpretive guides are also excellent for group exploration. For the
interpretive guides’ text, see the Interpretive Guides section.
The Junior Ranger Program
Although designed for families visiting the park during the summer season, the junior ranger
program can be adapted for use by organized groups. To become a junior ranger, the candidate
must complete a certain number of the activities in the junior ranger book and attend ranger-led
activities. Upon completion, the junior ranger earns a signed certificate and an official Junior

27. 26
Ranger patch. Junior Ranger books are available free of charge at park visitor centers and
campgrounds.

Activity Ideas for Children’s Groups – Specific Park Areas
Sieur de Monts Area
For a pleasant walk in the area, the Jesup Trail boardwalk and the Hemlock Trail combine to
make an easy one mile roundtrip. Through birch forest to meadow to towering hemlocks, three
different Acadia habitats can be enjoyed. In the opposite direction, another short loop takes you
through the woodlands and follows a stream to a pond called the Tarn.
Acadia National Park Nature Center
The Nature Center offers exhibits on the “science behind the scenery” of the park. Learn more
about the important work and tools of park biologists and researchers as they protect park
resources. In addition, the Nature Center offers an animal track matching game and taped frog
calls (fun to listen to). The lawn outside the Nature Center is a good location to let children run
and enjoy a picnic. A small bookstore is on-site. Free. Open from mid-May to mid-September.
Sand Beach Area
See how many different colors of “sand” particles can be found. Can they guess which ones
come from shells? What animals might those shells belong to?
Bubble Rock
The hike up South Bubble to Bubble Rock is appropriate for children ages five and up. Some
questions to ask along the route: Why is the forest almost all beech trees? How did Bubble
Rock arrive at this particular resting place? Will it stay here forever? What could make it fall?
Have students look for other evidence glaciers left behind. Please impress upon youngsters the
importance of staying on the trail, for both safety and resource protection.
Cadillac Mountain Summit
Match the surrounding panorama with the landmark names by using the interpretive signs.
Ship Harbor Trail
Have children compare life on the mudflat with life in a tidepool. Have students spread out
along the edge of the mudflat and use their senses to describe what life is like in the mud, on the
mud, or under the water when the tide comes in. Who visits the mudflat for food? What

28. 27
evidence of animals do they see? When visiting tidepools on the rocky point, have students sit
at different levels of tidepools and imagine what life is like under the seaweeds, on the rocks, in
the water. How are the different pools similar? How are they different? Where would they like
to live?
Carroll Homestead Interpretive Guide
Ask children to imagine what the Carroll children did at the Mountain House. What would life
have been like without TV, computers, cell phones, video games, and cars? Let them put
together a “Little House on a Maine Island” TV show based on their insights. For the
interpretive guide’s text, see the Interpretive Guides section.
Hiking trails suitable for children ages 5 and up:
• Great Head
• Gorham Mountain
• Beech Mountain
• Wonderland

PARK ACTIVITIES OVERVIEW
Bicycling
Carriage roads are suitable for mountain bikes or hybrids. The Park Loop Road and the primary
state routes bear heavy traffic, particularly in July and August. They should be used with
extreme caution. Bicyclists must obey all traffic regulations. Bike rentals are available in
nearby towns. For further information and trip planning, see the Park Activities In-
Depth/Bicycling/The Carriage Roads section.
Boating
A number of lakes and ponds on Mount Desert Island permit boating. There is a 10 horsepower
limit on Jordan Pond, Eagle Lake, Upper and Lower Hadlock Ponds, and Echo Lake. There is
no horsepower limit on Long Pond. All towns have launching areas for salt water near town
docks and municipal piers. The law requires you to carry a coast guard approved life vest for
each passenger. A better idea is to wear them. It could save your life! Canoes, kayaks, sailboats,
and motorboats can be rented in surrounding communities.
Boat Cruises (Privately Operated)
Cruises focus on the natural and cultural history of Acadia National Park and the islands off the
coast of Mount Desert Island. Trips vary in length from two to five hours. Most operate May
through mid-October. Cruise prices vary. Boarding is easiest at high tide when ramp-way
slopes are less steep. Contact the boat operators ahead of time to make arrangements for
assistance. One can remain in wheelchair on the lower deck of boats. For further information,
see the Park Activities In-Depth/Boat Excursions section.
Camping
There are two campgrounds in the park. All sites are wooded and within a 10 minute walk of
the ocean. The majority of sites are for tents, small and large, but other sites accommodate pop-
ups, vehicle campers, and RV’s up to 35 feet. A maximum of one vehicle and six people is
allowed at each site. There are no hook-ups. Campground facilities include comfort stations,
cold running water, dump station, picnic tables, fire rings, and water faucets. Showers and
camping supply stores are within 1/2 mile of both campgrounds. Private campgrounds are
available on the island. Contact local chambers of commerce for listings. For further
information, see Park Activities In-Depth/Camping section.
Carriage Rides
Wildwood Stables provides the tradition of horse-drawn carriage tours along the scenic carriage
roads in Acadia daily from early June to early October. The roads were built between 1913 and
1940 by John D. Rockefeller Jr., and are the best example of broken stone roads in the United
States. Wildwood Stables also offers a horse camp for visitors wishing to bring their horses
with them. There are no horse rentals in the park. Wildwood Stables is located on the Park
Loop Road, one-half mile south of the Jordan Pond House Restaurant. Reservations are
strongly recommended. Contact the stable directly at 1-877-276-3622. Two wheelchair
accessible carriages are available.

34. 33
Fishing
Freshwater fishing requires a Maine state fishing license for residents 16 years or older and
non-residents 12 years or older. Non-resident licenses can be purchased for the season or for
shorter periods in town offices and some local businesses. Ocean fishing requires no license. Be
cautious of surf conditions. Seaweed and algae covered rocks are extremely slippery. For
further information, go to the Park Activities In-Depth/Fishing section.
Hiking
Over 120 miles of trails and 45 miles of carriage roads cover Acadia National Park on Mount
Desert Island, as well as trails on Isle au Haut and Schoodic Peninsula. These range from easy
lowland paths to rugged mountain routes. Check the hiking descriptions in the recreation
section of this guide for more general information. For detailed descriptions of trails and
carriage roads, commercial guides and hiking maps are for sale at park visitor centers. For a list
of trails see the Park Activities In-Depth/Hiking section.
Interpretive Guides
Interpretive guides are available for two park sites, Carroll Homestead and Sieur de Monts. For
more information, go the Interpretive Guides section.
Museums/Nature Centers
The Islesford Historical Museum on Little Cranberry Island is open daily from late June
through September. Admission is free. The museum commemorates those who lived on the
Cranberry Islands and also preserves a part of the history of maritime New England. The island
is only accessed by boat. The museum does not have an accessible entrance. See the Driving
Through the Park/Park Sites Off Island/Islesford Museum section for more information.
The Abbe Museum at Sieur de Monts contains one of the finest collections of Indian artifacts
in the state. It is open daily from mid-May to mid-October. Although the museum is located in
the park, it is an independent and self-supporting nonprofit institution. A minimal admission fee
is charged. Special presentations will be made to groups with particular interests, but advance
arrangements are necessary. A special program is available for students. Call (207)288-3519.
Site does not necessarily meet ADA standards. Assistance may be needed for ascending steep
paved trail to museum and to enter the museum.
The Nature Center at Sieur de Monts includes exhibits about Acadia’s protective efforts
toward wildlife and plant species and offers some interactive exhibits for children. A book sales
area and information services are available. It is open weekends in May and daily June–
September; Hours from 9 a.m. to 4 p.m.
The Wild Gardens of Acadia, adjacent to the Nature Center, is a living field guide to Acadia’s
plants and associated habitats. Several habitats are represented with labeled plants to help
visitors familiarize themselves with Acadia’s vegetation. The Gardens are operated by Friends
of Acadia and are open dawn to dusk.

35. 34
Swimming
Lifeguards are on duty Memorial Day through Labor Day at Echo Lake (fresh water) and Sand
Beach (salt water). All sites have restrooms, changing rooms, water fountains and pay phones.
Sand Beach, located off Park Loop Road, offers ocean swimming. The water temperature
rarely exceeds 55 degrees. Thirty one steps lead to the beach. Access does not meet ADA
standards.
Echo Lake Beach, located on the west side of the island, offers a somewhat warmer
swimming experience. Other freshwater lakes located in the park serve as drinking water
reservoirs and are closed to swimming and wading. OK to good for accessibility but does not
necessarily all meet ADA standards. There is a gradual downhill paved path that goes to the
beach. A boardwalk goes over the beach to the water.
Tidepooling
Always consult a tide chart before planning your trip! Also take into consideration that on the
day of your trip, if seas are rough, tidepools may not be as exposed and extra caution for safety
is advised.
No tidepools meet ADA standards. The most easily accessed intertidal zone is on the gravel bar
between Bar Island and Bar Harbor at low tide. Automobiles may be driven onto the gravel bar.
Access is via a rocky and uneven ramp on Bridge Street in Bar Harbor. For further information
on tides, intertidal zones and intertidal life see Acadia’s Intertidal Zone.
Winter Activities
Cross-country skiing
Forty-five miles of carriage roads and forty-one miles of unplowed park roads are available for
cross-country skiing and snowshoeing. Skiing on hiking trails is not recommended because of
the uneven and steep nature of trails, ice falls blocking the path, and trail routes obscured by
snow. Ski equipment and rentals are available in some of the local communities. Ski tracks are
sometimes laid down by volunteers on sections of the carriage roads when snowfall exceeds
four inches. To learn more about carriage road routes see the Park Activities In-Depth/
Bicycling/The Carriage Roads section.
Snowmobiling
The Hulls Cove Visitor Center parking lot is a good beginning spot for visitors with
snowmobiles on trailers to unload and access the Park Loop Road.
• Snowmobile travel is allowed on the 27-mile Park Loop Road (except a one mile
section at Jordan Pond House), and most fire roads.
• Only two miles of carriage roads are open to snowmobilers as connector trails. The
remaining 43 miles are closed to snowmobilers. Stay to the right; all park routes are
two-way travel. Snowmobiles must display a valid state registration.
• Maximum speed limit is 35 m.p.h.
• Snowmobilers must use caution and yield the right of way to anyone not on a
snowmobile.

36. 35
• Towing people on skis or sleds is prohibited. It is illegal to operate a snowmobile while
under the influence of alcohol or drugs.

Overviews of the Scenic Drives
The Park Loop Road
A 27-mile paved road carries visitors through some of the most beautiful features of the park.
The road affords views of the Gulf of Maine and Acadia’s rocky coastline, winds through quiet
woods and around mountains, past large glacial lakes, and ascends Cadillac Mountain. The road
includes a 2.8 mile road from the visitor center to the loop section, a 13.5-mile one-way section,
and a 4-mile two-way stretch between Jordan Pond and Cadillac Mountain. The Cadillac
Mountain Road is 3.5 miles. Stay alert! In July and August, the road is crowded between the
hours of 10 a.m. and 3 p.m. See the Driving Through the Park/The Park Loop Road Overview
and the Driving Through the Park/Park Loop Road in Detail sections for more information.

38. 37
Westside of Mount Desert
Just south of Southwest Harbor, Route 102A provides access to another coastal section of
Acadia National Park. Sites of interest include a natural seawall, Seawall Picnic area, Seawall
Campground, Wonderland and Ship Harbor Trails, and the Bass Harbor Head Lighthouse. See
the Driving Through the Park/Westside of Acadia section for more information.
Schoodic Peninsula
1.5 hours “downeast” of Bar Harbor, it is the only part of the park located on the mainland. The
7 mile one-way loop road offers views of the rugged coast. See the Driving Through the

Sargeant Drive
In addition to the Park Loop Road, state and county roads offer scenic views. Sargeant Drive
skirts along the edge of Somes Sound. Access is from Northeast Harbor or off State Route 198.
Watch for small signs. See the Driving Through the Park/Other Park Areas on the East Side
section for more information.
The Park Loop Road Overview
Hulls Cove Visitor Center to Sieur de Monts
This 5 mile section includes Frenchman Bay views and quiet deciduous forests and meadows.
There are 4 overlooks: Frenchman Bay, Bar Harbor, 1947 Fire Overlook (views to Cadillac and
Champlain Mountains), and a view of the Porcupine Islands. Please turn off buses when
parking at overlooks or in parking lots. The noise and smell detracts from the experience of
park visitors. Plan 25 minutes with two overlook stops (15 minutes just driving time)
Sieur de Monts to Otter Point
This first section of the 14 mile one-way drive encompasses the exceptional scenery of
Acadia’s coastline before winding toward the island interior through towering spruce and pine
spires. The popular sites include the Precipice, Sand Beach, Thunder Hole, Otter Cliff, and
Otter Point.
Otter Point to Jordan Pond
The second section of the 14 mile one-way drive winds inland in the subdued quiet of a
beautiful spruce forest typical of the eastern side of Acadia before the fire of 1947. Plan a
minimum of 1 ½ hours with overlooks and one or two site specific stops. (25 minutes driving
time.) Highlighted sites include Fabbri Memorial, Otter Cove & causeway, Baker and Little
Cranberry Islands view, and Wildwood Stables.
Jordan Pond to the Cadillac Mountain Road
This 4 mile two-way section known as the Lower Mountain Road, allows for many more
people to experience some of Acadia’s most spectacular mountain and lake scenery. The
popular sites of the Jordan Pond area and Bubble Rock are located along this portion of the
Park Loop Road.
Cadillac Mountain Road to Cadillac Mountain Summit
The Cadillac Mountain Road is 3.5 miles and offers outstanding views all the way to the
summit. Plan 10 minutes, with two brief stops, to reach the summit.

The Park Loop Road Sections In Detail
Hulls Cove Visitor Center to Sieur de Monts
Hulls Cove Visitor Center
The visitor center is located off Route 3 in Hulls Cove, approximately eight miles from the
Trenton Bridge (leading onto Mount Desert Island) and 2.5 miles northwest of Bar Harbor. The
entrance to the visitor center parking lot, the accessible entrance parking lot, and start of the
Park Loop Road are clearly marked by a large Acadia National Park sign. The visitor center is
open from April 15 through October. Hours are 8 a.m. to 6 p.m. during July and August; 8 a.m.
to 4:30 p.m. or 8 a.m. to 5 p.m. other months. See the In-Depth/Hulls Cove Visitor Center In-
Depth section for more site information.
Distances are measured from the visitor center.
MILE .4
Frenchman Bay Overlook (Appropriate for tour bus groups to get off the bus.)
Description: The bay stretches seven miles north from its Gulf of Maine headlands, bordered to
the west by Mount Desert Island and to the east by Schoodic Peninsula. One of the interpretive
signs at the overlook labels the view of islands and mountains.
Parking: The overlook provides 15 diagonal parking spaces. There is no parking for buses.
General site information: Frenchman Bay’s name reflects the area’s historic French influence.
L’Acadie, the French title for this region, most likely originated from the name Arcadia. That
title was bestowed in 1524 by Giovanni de Verrazano, the Italian navigator sailing for France,
to describe present-day Chesapeake Bay and the Outer Banks of North Carolina shore scenery.
It was a cartographer’s mistake that placed Arcadia well north of the coastline that had
reminded Verrazano of ancient Greek landscapes with beautiful green forests. For more
information about the French history see the history section.
At mile 1.7 is a turn-off to the left that leads to Bar Harbor.
MILE 2.2
1947 Fire Overlook (Passengers can remain on bus.)
Description: To the far left is Frenchman Bay and to the far right is Sargent Mountain. The
view straight ahead includes: in the foreground, the summits of Cadillac and Dorr Mountains,
and in the background, Champlain Mountain. This area is mostly deciduous as a result of the
1947fire that burned 17,000 acres on the eastern side of Mount Desert Island. 10,000 acres were
park land. As you gaze toward the mountains, look closely at the variation in the vegetation on
the hillsides. The conifers’ dark green hue contrasts against the hardwoods’ bright green leaves,
autumn colors, or bare branches. Can you detect what portion burned in 1947? As you travel
the Park Loop Road, watch for changes in forest cover from deciduous woods to red spruce.
See the fire of 1947 section for further information.
Parking: Small pull-off without true parking spaces; parallel parking. Note: interpretive sign.

40. 39
MILE 2.4
Turn-off to the left for Route 233. To leave the Park Loop Road and access Northeast Harbor or
the west side of the island, take a right on Route 233; a left turn leads to Bar Harbor.
MILE 2.8
Junction with the loop section. To the left is the one-way section of the loop heading toward
Sieur de Monts and Sand Beach; straight ahead is access to Cadillac Mountain Road and Jordan
Pond.
After turning onto the one-way section of the Park Loop Road, there is no parking in the right
hand lane until Beaver Dam Pond. Be alert to cars and cyclists. This area is extremely
congested in July and August.
MILE 3.2
Porcupine Islands Overlook: During the busy summer months, this overlook is used for
parking to hike the North Ridge of Cadillac Mountain. Expect only to slow down and point out
the islands. The islands are visible from various locations along the Park Loop Road.
Description: This overlook of Bar Harbor and Frenchman Bay provides a good view of Bar
Island and the Porcupine Islands. From left to right (west to east): Bar Island, Sheep Porcupine,
Burnt Porcupine, Long Porcupine, and Bald Porcupine. A good way to remember the Porcupine
Island names is the phrase: Sheep Burnt Long go Bald. At low tide a sand bar is exposed
allowing access to Bar Island. Bar Island, as well as Sheep, Long, and Bald Porcupine Islands
are part of Acadia National Park.
Porcupine Islands Overlook to Great Meadow
Traveling from this overlook to Sieur de Monts you pass through an area that burned in 1947.
The forest today is primarily a birch and aspen forest. At mile 4.7 and mile 5.0 are turn-offs to
the left which lead to Bar Harbor. At mile 5, on the right is the exceptionally scenic view of
Great Meadow which is flanked by two sets of mountains. Dorr and Cadillac Mountains rise to
the right of the meadow. Huguenot Head and Champlain Mountain are to the left. Each of these
mountain pairs are connected by a notch formed during the last glacial retreat. As the ice sheet
receded, a meltwater channel of raging water formed inside the ice, etching a deep notch in the
granite ridges defining two individual mountain summits.
MILE 5.3
Sieur de Monts: Considered “The Heart of Acadia” by the park’s founding father, George B.
Dorr, this area is home to the Sieur de Monts Nature Center, The Acadia Wild Gardens and the
Abbe Museum. There are also numerous walks and hiking trails. Parking can be difficult to find
in the summer months. To avoid the crowds, consider visiting the site early in the morning of
last in the day. See the In-Depth/Sieur de Monts Area section for more information.
Sieur de Monts to Otter Point
The following are suggested minimum times to get off the bus, enjoy the site, use restrooms if
necessary, and re-board the bus. Considerably more time can be spent at these locations if
desired.

41. 40
• Precipice: 10 minutes, if interested in learning about or watching peregrines
• Sand Beach: 45 minutes, depending on your group
• Thunder Hole: 20 minutes, depending on your group
• Otter Point: 30 minutes, if walking a portion of the Ocean Path
MILE 5.8
Bear Brook Picnic Area originally served as the park’s first campground.
MILE 5.9
Beaver Dam Pond, across from the picnic area. Three beaver lodges and a dam can be seen.
Champlain Mountain is to the left behind the pond; Huguenot Head is to the right. Jackson
Laboratory, the world-renowned research facility in genetics and mice breeding for research is
on the opposite side the road.
MILE 6
Ocean views begin just up the hill, after the pond. Frenchman Bay, Egg Rock Lighthouse,
Schoodic Peninsula, and the Acadia coast can be seen. Schoodic Peninsula is part of Acadia
National Park. The 2,266 acre parcel is a one-hour drive from Mount Desert Island to the
northeast. It is next to the town of Winter Harbor. Egg Rock, the island with a small lighthouse,
is visible between Schoodic Peninsula and Mount Desert Island. The lighthouse was built in
1875, but now is completely automated like all Maine lighthouses.
Highseas Estate, the large “cottage” along the shore, was built in1912. It stands as a symbolic
remnant having survived the fire of 1947 which raged around it. Protective efforts saved it from
the flames. Today, it serves as summer housing for Jackson Lab employees. Despite stories,
there is no documentation that connects the estate with a passenger on the ill-fated Titanic.
MILE 7.5
The Precipice parking lot is on the right. The Precipice Trail, with its narrow ledges and iron
rung climbs, is one of Acadia’s most exciting and difficult trails. During the late spring and
early summer, if peregrines are nesting, the trail is closed to protect both visitors and the
falcons. Visitors may have a chance to spy the peregrines with the help of a park ranger. When
the trail is closed, spotting scopes and informal interpretation are available in the parking lot
during the morning hours to help visitors learn more about these incredible birds.
MILE 8.1
Sand Beach Entrance Station: Entrance fees paid at the entrance station return to the National
Park Service for specific projects.
MILE 8.7 – 10.5
Ocean Drive: Views along the Park Loop Road open to the breathtaking interface between land
and sea that defines Acadia for many visitors. There are numerous parking lots along this drive.
Parking in the right lane is permitted unless otherwise signed.
While along the Ocean, protect yourself and your park

42. 41
• Stay back from the water’s edge. Never turn your back to the ocean. Waves are
unpredictable and can knock you down.
• Do not feed wildlife. This includes gulls. Feeding only exacerbates the problem of
wildlife depending on humans to feed them.
• Picnics are popular all along the shoreline. Please remember to take all trash out with
you, even orange peels, apple cores, peanut shells, etc. They are inappropriate for
wildlife to eat and look unsightly.
MILE 8.7
Sand Beach: Wide expanse of broken shell and sand beach in Newport Cove. See the In-
Depth/Sand Beach section for more information.
MILE 8.7-10.7
Ocean Path: Level pathway paralleling the Park Loop Road for those preferring to walk. The
path is 2.2 miles from the Sand Beach parking lot to Otter Point. The path begins from the
upper lot of Sand Beach. As an example, those wishing to walk could meet the rest of their
party at Thunder Hole. Walking along the Ocean Path follows a favorite walking route of
rusticators and cottagers who reveled in the shoreline sites. A popular excursion in the mid-to
late 1800s was to Thunder Hole. Poison ivy grows along the Ocean Path in some sections.
MILE 9.4
Thunder Hole: Rocky chasm that thunders when surf is heavy. There is a small parking lot at
the gift shop. Many people choose to park in the right hand lane of the Park Loop Road. Bus
parking is designated in the right hand lane.
Accessibility: Thunder Hole has an accessible viewing platform. Thunder Hole gift shop is not
accessible.
Description: Thunder Hole often elicits only a sloshing gurgle, but under appropriate
conditions, it does indeed bellow. The best time to try to experience Thunder Hole’s boom is
two hours before high tide or during storms. What makes Thunder Hole thunder? When ocean
waves slap against this narrow chasm, air becomes trapped deep in its chamber. When released,
a booming sound results from the once-trapped air. Its thunderous rumble is accompanied by
plumes of ocean spray. During strong storms, the steps to Thunder Hole are closed. But its
booming and resulting spray can be seen and heard from a distance. Waves can be
unpredictable and visitors should take appropriate precautions.
MILE 9.7
Gorham Mountain Parking Area (1.8 mile, moderate trail)
MILE 9.9
Otter Cliff Road and access to the Fabbri Picnic Area: Otter Cliff Road leads to Route 3. A left
turn on Route 3 leads to the town of Otter Creek and Blackwoods Campground; a right turn
leads back to Bar Harbor.
